I could not see any remnants. I just removed the driver side cover and didn't see anything. I have a breather and a PCV, but the PCV may be bad so I disconnected the hose and plugged it. The valve covers do have the baffles.I tried looking for the seals, but it looks like it has an inner and an outer valve spring and I can't even see the valve stem.
I called the auto parts store and they wanted $46 for a compression tester, which seems high to me. So I will try to bum one off somebody.
